Voltage) as amended by 93/ 68/ EEC (CE Marking). However, electri-
cal noise or intense electromagnetic fields in the vicinity of the equip-
ment may disturb the measurement circuit. Measuring instruments will
also respond to unwanted signals that may be present within the
measurement circuit. Users should exercise care and take appropriate
precautions to avoid misleading results when making measurements
in the presence of electronic interference.
